SED2 AOP Operating Instructions

22 Siemens Building Technologies

Timer Function

NOTES:

1. Before using the timer function as a control method, set the AOP real time clock as described

in the Set Time/Date section.

2. Setting a timing event for ‘every day’, configures the same event for each day of the week

separately. To clear an ‘every day’ event, you must clear the event individually from each

day.

3. When multiple events must be cleared from the Timer function, it may be easier to reset the

AOP as described in the AOP Reset section.

4. When in Master mode of operation and viewing the connected SED2 drives, a ‘T’ displays in

the top left corner to indicate that the connected SED2 drives are under timed remote control

and may start or stop unexpectedly.

Setting the AOP Timer

When in local or master mode, you can access the timer feature from the main menu. The timer

operates as a 7-day, time-of-day, on/off controller (much like a central heating controller but with

the addition of a possible multi-VFD selection).
